Chatan

Chatan (Nakagami District) is a coastal base on Okinawa, where scuba diving is mainly about easy access to the surrounding North Pacific / coastal waters. Dives from local operators typically focus on reef areas close to shore and day trips to nearby sites, with conditions that can change with the season and currents. Expect a mix of training-friendly spots and more challenging dives depending on depth and visibility on the day. As with many Okinawan locations, marine life varies by site, and choosing the right conditions for your experience level matters—especially for current, surge, and entry/exit options.
